COUPLER RELEASE RIGG-ING.

Application filed September 23, 1922.

To all whom it may concern:

Be it known that I, STERLING H. CAMP BELL, a citizen of the United States of Ameriea, residing at the city of St. Louis, State of Missouri. I nited States of America, have invented a certain new and useful Coupler Release Rigging, of which the following is such :i to ll. clear, and exact description-as Will. enable anyone skilled in the art to which it nppertains to make and use the same, ref creme being had to the accompanying drawings, forming part of this specification.

lily invention relates to a coupler release rigging and particularly to that type of rigging in which the operating arm is provided with a vertical eye in which the link connecting it with the coupler lock pin has sliding movement.

The object of my invention is to so construct a release rigging of the type above referred to that the link may be attached to or detached from the coupler lock pin while the actuating rod is in position on the car and. at the same time, Lo effectively prevent accidental disengagement of the link and pin during service movements of the parts.

In the accompanying drawings which illustrate one form of my device, Figure 1 is a top plan view,on a reduced scale, oi" one end of a railwzrv car to which one form of my device is applied: Figure 2 a front view of the operating arm and lock pin, together with their connecting link; and Figure 3 is a side view of the part shown in Figure 2.

indicates a railway car provided with the usual draw head 11 having a coupler loclc pin 12. Revolubly mounted in brackets 13. secured to the end of the car i0. is the actuating rod 14 having a forwardly projecting operating arm 15 terminating in a vertt cal eye 16. Sliding in the eye 16 is a link 17 having at its upper end a head 18 of such size as to be incapable oi passing through the eve 16. The lower end of the link 11" terminates in a loop 19 having a passage 20 of such size as to allow the insertion of the loop into, or its removal from. the eye of the lock pin. The link and pin may thus be engaged or disengaged while the actuating rod 14 is in position on the car. In order to prevent the accidental disengagement oi? the link and pin during service movements of the car, I provide closing means for the passage 20, one form of which will now be described.

Serial No. 590,061.

The link 17 is provided between the head 1? and the loop 19 with a threaded portion 30. The threaded portion is made larger than the body of the link so that the nut 31 may be run beyond the threaded portion to close the passage 20. lVhcn in this position, the passage 20 can only be uncovered by bringing the threads on the nut and stem carefully into alignment and then turning the not. H the nut is accidentally raised against the threaded portion it is evident that it will at the same time be canted with relation to the stem so that rotation of the nut in this position will not uncover the passage.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent 01'' the United States is:

I. In a device of the class described, the combination with an operating arm, of a link engaged with said arm, a loop on the lower end oi said link for engaging with the coupler loch pin, and a loop closing member having threaded engagement with said link.

2. In a device of the class described, the combination with an operating arm, of a link engaging with said arm, a loop on the lower end of said link for engaging with a coupler lock pin, and a loop closing member having threaded engagement with said link, said member being adapted to be moved out of threaded engagement with the link when in locked position to prevent accidental release.

In a device of the class described, the combination with an operating arm provided with a vertical eye, of a headed link movable in said eye and provided with a. threaded portion intermediate of its length, a loop on the lower end of said link for engaging with a coupler lock pin, and a loop closing member on said threaded part.

In a device of the class described, the combination with an operating arm provided with a vertical eye, of a headed link movable in said eye and provided with threaded portion intermediate of its length, a loop on the lower end of said link for engaging with a coupler lock pin, and a loop closing member on said threaded part. said member being adapted to be moved beyond the threaded part to close the loop.

In testimony whereof, I have hereunto set my hand and afilxed my seal.
